Calendar Functions for dates starting in 1582
Hi all.

Pretty much the majority of calendar functions programs for HP-67/97 start with the year 1900.

Are there calendar function programs which work with dates as early as 1582?

Also, is there an algorithm for the 67/97 which calculates a date + or - from date on or after 1582?

Thanks
